and is the LPP a 3" or a 2.5" pipe. I hear I will have some low end problems with a 3" pipe.

i was lookin at the lpp headers thre a great price but i was wonderin if id have a problem with them being no egr on a 2004 chevy 1500 with the 5.3 i believe its a lm7 not my truck so im not rly sure we just started lookin into these things for his truck

 

ok this is my new plan.I am going to go with the LPP headers, but i would like to get a 2.5" Y and have cats welded in. what do you think? where can i find a 2.5" y pipe?

 

You could always have one custom made.
